Class PartitionGridRouterStage

java.lang.Object
  y.layout.AbstractLayoutStage
      y.layout.router.PartitionGridRouterStage

All Implemented Interfaces:

Layouter, LayoutStage

public class PartitionGridRouterStage
extends AbstractLayoutStage

Layout stage for OrthogonalEdgeRouter that should be applied when routing edges in a partition grid. Note: This stage can only be applied if all nodes are contained within a single partition grid, i.e., edges can never cross the border of the partition grid.

Constructor Detail

PartitionGridRouterStage

public PartitionGridRouterStage()

Creates a new instance of this class.

PartitionGridRouterStage

public PartitionGridRouterStage(Layouter coreLayouter)

Creates a new instance of this class.

Parameters:

coreLayouter - the core layouter invoked by this stage. The coreLayouter must contain an instance of OrthogonalEdgeRouter in its layout pipeline.

Method Detail

canLayout

public boolean canLayout(LayoutGraph graph)

Description copied from interface: Layouter

Returns true iff the given graph can be laid out by this algorithm. Calling doLayout with the given graph as its argument will only success if this method returns true.

doLayout

public void doLayout(LayoutGraph graph)

Main layout routine.

Precondition:

the coreLayouter must contain an instance of OrthogonalEdgeRouter in its layout pipeline. Furthermore all elements have to lie inside the partition grid.
